yeah,
haven't talked to him today and unfortunatly am in napier all day tomorrow and thursday so it wont be untill friday untill i go and do more tests for him, he should have the ph fine by then and done one water change so hopefully they will hold out untill i can help more.
if there is no biological filter should he do smaller more frequent water changes? say, 5% to 10% every day or every second day?
Thanks for all your help
Daniel
